Abstract

The invention belongs to the field of cables, and particularly relates to a lightning protection photoelectric cable. The cable comprises a core wire, a communication layer, an inner insulating layer, a metal sheath, an outer insulating layer and a sheath layer which are sequentially arranged from inside to outside, the core wire is a conductive wire, and the communication layer is provided with an optical fiber wire. The lower end of the communication layer is provided with a recessed groove, the inner insulating layer is provided with a protrusion matched with the recessed groove, and the position, corresponding to the recessed groove, of the inner insulating layer is provided with an installation groove. The metal sheath comprises a sheath member and a plurality of shielding wires. The sheath member is provided with a gap, and the plurality of shielding wires are arranged on the outer surface of the inner insulating layer corresponding to the gap of the sheath member. The sheath part is provided with a clamping part corresponding to the mounting groove, and the clamping part is inwards inserted into the mounting groove; the outer insulating layer is encapsulated on the outer side of the metal sheath, and the sheath layer is coated on the outer side of the outer insulating layer. According to the optical cable, the lightning protection performance of an existing optical cable is effectively improved; the lightning protection performance is greatly improved by reducing the electrostatic charge residue of the whole optical cable, and the lightning stroke risk of the optical cable is reduced.

Description

Technical field [0001] The present invention belongs to the field of cables, in particular to a lightning protection photoelectric cable. Background [0002] Optical cable is a functional cable that realizes both optical signal transmission and power transmission, and is a common and versatile cable with strong use value. [0003] In some special laying environments, optical cables also need to further meet a variety of performance requirements. For example, the submarine optical cable laid on the seabed needs to meet the performance of high voltage resistance, waterproofness, bite resistance, etc., and the optical cable erected across the sea needs to meet the performance of high distortion resistance and high strength, and in some areas with high lightning incidence, it is necessary to meet good lightning protection performance. [0004] Usually the means of light cable for lightning protection is to set the lightning protection wire. However, due to the fact that some areas ar...
